EDWIN J. NIXSON, OF LOS ANGELES, CALIFORNIA; ASSIGNOR OF ONE-HALF T0 FLORENCE MILLS NIXSON AND ONE-HALF TO JEROME CARLTON JOHNSON,

BOTH OF LOS ANGELES, CALIFORNIA.

AVIATOR/S To all whom it may concern:

Be it known that I, EowrNJosEPH N IXSON, a citizen of the United States, residing at Los Angeles, in the county of LosAngeles and State of California, have invented new and useful Improvements in Aviators"Goggles of which the following is a specification. I

My object is to make improved goggles for the use of aviators, chauffeurs, and the like, and my invention consists in the novel features herein shown, described and claimed.

perspective of aviators gog- Figure l is a g I the principles of my invengles embodying tlon.

Fig. 2 is an enlarged fragmentary horizontal sectional detail on the line 2-2 of Fig. 1.

Fig. 3 is a vertical sectional lines 33 of Figsql and 2.

Fi 4 is a perspective of one eye glass or lens.

Fig. 5 is a perspective of the innerfraine of a glass or lens.

Fig. 6 is a perspective of the outer frame.

Fig. 7 is a fragmentary sectional perspective on the line 7-7 of Fig. 6.

he eye glasses 1 and 2 are made interchangeable in configuration and in other respects are substantially alike.

The glass 2 shown in Fig. 4 and in crosssection in Figs. 2 and 3 comprises two plates 3 and 4: cut to the same configuration and curved and ground to fit one upon the other. and the plates are secured together by a sticky, transparent cement 5 and this cement is preserved in an elastic sticky condition by applying a water-proof coating 6 all around the edges of the plates so as to prevent the cement from evaporating and drying. The completed glass or lens is intended to permit a clear vision without either magnif ing, or distorting. The two plates 3 and 4 cemented together makes a strong glass, window, or lens .which will not splinter and fly to pieces easily, it being possible to break either the inner plate or the outer plate into many pieces without having the pieces come loose from the opposite plate and without breaking the opposite plate. The completed glass 2 has a comparatively straight upper edge 7 a comparatively detail on the Specification of Letters Patent. Application filed February 21, 1918.

straight lower edge 8, a rounded outer end 9, the inclined edge 10 leading downwardly and inwardly from the end of the edge 7, and the inclined edge 11 leading upwardly and inwardly from the end of the edge 8, said edges 10 and 11 meeting near the center.

The glasses 1 and 2 are made large enough to coinpletely'cover the cavity of the eye so asto provide unobstructed vision vertically and longitudinally in either direction.

The'inner frame 12 shown in Fig. 5 is made of thin aluminum and is shaped much like the glass, there being a central opening 13 slightly smaller than the glass 2 and there being bolt holes 14 distributed at suitable points around the opening 13 and numerous ventilation openings 15, and there being a vertical slot 16 in the upper inner corner and a pairof vertical slots 17 and 18 at the outer end.

The outer frame 19 shown in Fig. 6 is of the samev configuration as the frame 12 except that it has an off-set inner edge 20 providing a seat for the edge of the glass 2, there being a central opening 21 through the plate registering with the opening 13, bolt holes 22 registering with the bolt holes 14, ventilation openings 23 registering with the openings 15, a slot 24 registering with the slot 16, and slots 25 and 26 registering with the slots 17 and 18.

The glass 2 is placed in the seat 27 so as to cover the opening 21, and the frame 12 is placed against the outward side of the glass, and bolts 28 are inserted through the bolt holes 14 and 22 and nuts 29 applied to hold the frames together.

The glass or lens 1 is mounted in the same manner as that already described with reference to the glass or lens 2, the only difference being that the frames 30 and 31 thus produced are made right and left.

The two frames are connected together by a double jointed hinge 32. The hinge 32 comprises a metal strap bent to form the central portion 33, ends 34 and 35 extending from the central portion at right angles, and hooks 36 and 37 extending from the ends 34 and 35. The strap is bent U-shaped, then the ends 34 and 35 are inserted from the front side through the openings 16 and 24 in the two frames 30 and 31 and then the inner the wearer, the

a soft, non-metallic the band 40 will keep ends are bent toward each other to form the hooks 36 and 37. V

The portions 38 and 39 of the joined frames, together with the hinge 32, are adapted to bridge the nose of inner QClgBSOf the frames being close together. H

An elastic strap 40 is inserted back and forth through the slots 17,25, 18. and 26 in the frame 31 and sewed upon ltself and then passed around back and forth through corresponding slots in the frame 30 and is held by a buckle ll or the like, so that the size of the strap may bereadily adjusted to fit the 'wearers head. i A binding as of plush, fur, or the like, is bent aroundthe edges of the frames and secured in place by stitching through some of the perforations 15 and 23, so as to form cushion between the metal frames andthe face of the wearer.
